      Align:
      <button id="leftsides">Left Sides</button>
      <button id="rightsides">Right Sides</button>
      <button id="tops">Tops</button>
      <button id="bottoms">Bottoms</button>
      <button id="cenX">Center X</button>
      <button id="cenY">Center Y</button>
      <button id="row">Row</button>
      <button id="column">Column</button>
      </br>
      Rotate:
      <button id="45">45°</button>
      <button id="-45">-45°</button>
      <button id="90">90°</button>
      <button id="-90">-90°</button>
      <button id="180">180°</button>
      </br>
      Z-Order:
      <button id="front">Pull to Front</button>
      <button id="back">Push to Back</button>
      </br>
      Arrow Mode:
      <input type="radio" name="arrow" id="move" checked="checked">Move</input>
      <input type="radio" name="arrow" id="select">Select</input>
      <input type="radio" name="arrow" id="scroll">Scroll</input>
    </p>
    <p>
      This example demonstrates a custom <a>CommandHandler</a>.
      It allows the user to position selected Parts in a diagram relative to each other,
      overrides <a>CommandHandler.doKeyDown</a> to allow handling the arrow keys in additional manners,
      and uses a "paste offset" so that pasting objects will cascade them rather than place them on top of one another.
      It is defined in its own file, as <a href="DrawCommandHandler.ts">DrawCommandHandler.ts</a>.
    </p>
    <p>
      The above buttons can be used to align Parts, rotate Parts, or change the behavior of the arrow keys.
    </p>
    <p>
      Usage can also be seen in the <a href="../projects/bpmn/BPMN.html">BPMN Editor</a> sample.
